摘要
由 Pseudomonas cannabina pv. alisalensis（Pcal）引起的细菌性叶枯病（BLB）是一种毁灭性病害，在过去二十年中已在全球蔓延。Pcal 可感染所有甘蓝作物，每年都会导致美国东南部甘蓝叶菜产量损失。目前还没有抗 Pcal 的芜菁菜商业栽培品种，也没有有效的杀菌剂。我们报告了首次在 Brassica rapa L. 中鉴定出对 Pcal 引起的细菌性叶枯病的抗性来源。我们在温室试验中对美国农业部的芸苔属品种（275 个品种）进行了多次筛选。测试的三个商业栽培品种在所有测试和复测中表现出中等反应。在 B. rapa 种质资源库中发现了三个具有显著抗性的品种（Ames 7572、PI 649171 和 PI 649183）。这些已鉴定的品种是培育抗 Pcal 油菜栽培品种和将抗性基因座导入油菜栽培品种的重要来源。
Novel sources of resistance to bacterial leaf blight in the USDA Brassica rapa collection
Bacterial leaf blight (BLB), caused by Pseudomonas cannabina pv. alisalensis (Pcal), is a devastating disease that has spread worldwide over the past twenty years. Pcal can infect all Brassica crops and leads to yield losses of Brassica leafy greens across the Southeastern US every year. There are no commercial cultivars of turnip greens with resistance to Pcal and no effective bactericides available. We report the first identification of resistant sources in Brassica rapa L. against bacterial leaf blight, caused by Pcal. The USDA accessions of B. rapa (275 accessions) were screened through multiple tests in greenhouse trials. The three commercial cultivars tested exhibited an intermediate response across all tests and re-tests. Three accessions (Ames 7572, PI 649171, and PI 649183) with significant resistance were identified in the B. rapa germplasm collection. The identified accessions are an important source for development of B. rapa cultivars resistant to Pcal and introgression of the resistant loci into B. napus cultivars.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
